Answer:
Answer is Option 2
Step-by-step explanation:
Triangles equal to 180 degrees in total. So it is 55+54+x+74=180
The simplified version that I just wrote is Option 2
It would be 1/5, 5/8, 2/3 because 1/5 is 24/120, 2/3 is 80/125, and 5/8 is 75/120
we want area =circumference*something
dividing our first equation by 2*pi
substituting in the second equation
simplifying
Answer:
(a) It is a function.
(b) D = [1,2,3,4,5]
(c) R = [40,80,120,160,200]
Step-by-step explanation:
(a) Is this a function?
Yes, in order to be a function we need two groups, in this case "time in days" and "total cost". From this group the first one is called the domain, while the other one is called range. The elements in the domain can only have one associated element in the range. By this definition the graph displays a function.
(b) What is the domain?
The domain of a function are the numbers which represent the possible input. In this case it is the group of integer numbers from 1 to 5, in order words D = [1, 2, 3, 4, 5].
c) What is the range?
The range is the group which represent the output of the function and in this case it is the group R = [40, 80, 120, 160, 200]
